It’s the Y-shaped flashing light device (powered by 1.21 jigowatts) that turns a sports car into a time machine. How does/did it work? “Doc” couldn’t even explain it:

It is not described in the films exactly how the flux capacitor worked beyond that of a typical plot device or a typical deus ex machina device, though Doc mentioned at one point that the stainless steel body of the DeLorean has a direct and influential effect on the “flux dispersal”, though he was interrupted before he could finish the explanation. The flux capacitor required 1.21 gigawatts of electricity to operate.

You can make your very own Flux Capacitor (but, PLEASE, do not toss it in your car, cross your fingers, and go 88 mph in a parking lot). Instructables has the instructions. Not a lot of electronics experience is needed, and most of the equipment is available at your local hardware store and Radio Shack. The Flux is housed in an ordinary fuse box.

Too complicated? You can buy one here for $250. A small price to pay for time travel capabilities. And this (more-expensive) dealer will even provide a time-travel, money back guarantee (read closely):

This item may be expensive, but can you place a price on time travel? NOTE: Special return policy: If you are not 100% satisfied, you may return this product for a full refund, in no LESS than 30 days before you purchase it!

Once you have have your Flux, get started on the rest of the De Lorean time machine:

The Navy said yesterday that on Tuesday the mission, named Stellar Scorpion, was blessed at the Barking Sands missile facility by "Uncle Tom" Takahashi, who named the Lake Erie’s two interceptor missiles "the crashing sound of the ocean" and "the ear of the earth," respectively.

Being a decommissioned helicopter-carrier, the USS Tripoli (photo above) seems like a pretty odd choice to be involved in this exercise. The "Semper Princeps" (Always First), as they call it, has been around since 1964, and decommissioned (but strangely still very active) since 1995:

She was decommissioned in 1995 and as of 2004, she was on loan to the Army, but remained laid up at Mare Island Naval Shipyard. In December 2006, the ship was towed to Pearl Harbor, Hawaii, where it now has a high-tech role as a launch platform with the nation’s developing ballistic missile defense program. Three times the ship was towed some 100 miles off shore and used to launch small ballistic missiles, which are then intercepted by Terminal High Altitude Area Defense Missiles, test-fired from the Pacific Missile Range Facility. The last test in the series was performed October 26, when the ship fired a "scud-like" missile, which was successfully intercepted. The ship will be towed back to the San Francisco Bay Area for the winter. Kaua’i lacks a suitable land-based launch site, and the costs of building one would far exceed the approximately $600,000 per year it costs to use the old warship, so the vessel will return to Pearl Harbor for a second series of tests in late spring 2008.

Out in the bush, you need an airplane to get around effectively. You can get by with a snowmoble in the winter, but how much can you cover in a day? Alaska is a big state, spanning 663,267 square miles (that’s 367 million acres, cowboy). Since the early 1970s, Alaska’s telephone system has been using satellite, primary using AT&T Alascom’s Aurora satellites (currently Aurora III; co-named AMC-8). Pretty extensive network, highlighted by the Alyeska Pipeline:

When Galaxy 18 launched in May, we didn’t think they’d be cutting over some of the services from the Galaxy 10R spacecraft so quickly. End-of-life for G10R was originally projected to be 2015, but after a XIPS problem, it was cut short. One of the big customers on that bird, GCI, moved nine transponders of traffic yesterday:

GCI announced today that it successfully transitioned all of its rural telecommunication services last night to the Galaxy 18 satellite. This satellite will provide long-distance, Internet, distance education and telehealth services throughout rural Alaska for the next 14 years.

“The success of last night means rural Alaskans will stay connected to the most advanced network in Alaska,” said Ron Duncan, GCI president and CEO. “It also provides major businesses in Alaska and carriers in the lower 48 states the ability to directly touch customers virtually anywhere in Alaska.”

GCI owns nine transponders on Galaxy 18 and will take possession of a tenth transponder in approximately two weeks. GCI will lease the transponder capacity from Intelsat. However, GCI will be required to account for this arrangement as a capital lease. This will result in a capital lease obligation, and corresponding long-term asset, in the approximate amount of $98 million.

Hmm. At that price, it seems to work out to approximately $58,000 per month per transponder, and that ain’t a bad price. I suppose if the oil keeps pumping, there will always be money to pay for satcom services. Keep us rocket scientists busy for years.

Two XH-150 prototypes are returning this week to the Seattle area after being unveiled at the North American International Auto Show in Detroit and then traveling to cities across the U.S. to demonstrate the car to carmakers, government officials and the driving public, including a ride-and-drive demonstration on Earth Day for members of Congress in the Nation’s Capital.

Road tests of the XH-150 at Michelin’s Laurens Proving Grounds in South Carolina prior to the Detroit unveiling demonstrated extreme fuel economy without sacrificing performance. Test reports indicated the XH-150 traveled 41.9 miles without burning an once of fuel in a mixed urban/highway driving cycle, achieved all-electric highway speed of 87 MPH, accelerated faster to 60 MPH than comparable gasoline-only models (11.6 seconds) and, in full hybrid mode, delivered zero to 60 in just 6.9 seconds. Along with dramatically reducing vehicle emissions, the XH-150 is expected to significantly reduce the cost of operating a car. It uses only one dollar of off-peak electricity to provide enough power for the average driver’s 40 miles of daily driving and can achieve 150 miles per gallon during a typical 340 mile week. No other hybrid or plug-in hybrid of which AFS Trinity is aware has demonstrated the ability to achieve such fuel economy, range, highway speed and acceleration.

The Governor of Washington, along with local and state officials, will be tooling near South Lake Union in Seattle today to celebrate the homecoming of the incredible vehicle.

Seven astronauts who will fly into orbit aboard space shuttle Discovery will have comfortable seats for the climb into space. An eighth space ranger won’t have a seat at all. In fact, he will be packed tight inside a box and won’t even get to enjoy the ride up.

But it’s nothing veteran spaceman Buzz Lightyear can’t overcome.

The good news is that he’ll have some sports shows to listen to, along with a host of jerseys that have been to the Champs Elysees in Paris for the Tour de France and to the Super Bowl.

More accustomed to soaring among the galaxies on fold-out wings and a backpack rocket, Lightyear will take to space on Discovery’s STS-124 mission stowed inside a locker in Discovery’s crew compartment. The 12-inch-tall action figure is flying as part of a partnership between NASA and Disney Parks to encourage students to pursue studies in science, technology and mathematics, one of NASA’s main educational goals.

Disney’s Youth Educational Series and NASA have developed an online program known as the Space Ranger Education Series. It includes fun educational games for students, as well as materials for educators to download and integrate into their classroom curriculum.

No, the title of this post isn’t a reference to the velocity of our Kerouacian prose — it’s what you could be doing if you took a train between Paris, Brussels, Amsterdam and Cologne:

The first commercial application of the European Space Agency (ESA) “Broadband on Trains” initiative officially launched May 14 on six high-speed Thalys trains… Passengers on the trains equipped with “Thalysnet” have continuous Internet connectivity while traveling at 300 km/h via a satellite 36,000 km above the trains.

The satellite link uses a low profile tracking antenna on the train to provide a two-way connection to the Ku-band satellite system and a hub station connected to the Internet backbone. Terrestrial wireless is used to maintain a connection when the train is traveling through tunnels. The total bandwidth from the satellite shared among users on the train is 2 Mbps down and 512 Kbps up. Bandwidth across all trains in the fleet is allocated on demand according to the usage level.

The tracking antenna truly is low-profile. If a train passes you at high speed, you’d be hard pressed to see the little nub whizzing by you:

Thalysnet… was developed by a consortium lead by Nokia Siemens Networks, which combines satellite communications with conventional wireless data technologies to provide a continuous Internet connection on board trains travelling across national borders at 300 km/h. One of the companies in the consortium is the UK-based 21Net, which carried out a pilot project in 2005 under the European Space Agency’s Broadband to Trains initiative.

21Net worked with leading railway operators such as RENFE (Spain) and SNCF (France), along with Thalys, to develop a solution combining bi-directional satellite communications with terrestrial wireless technologies.

With soaring gas prices leading to an increase in public transport usage here in the US, could an American equivalent of Thalysnet be far behind?
